Re: [Tinycc-devel] variable value changes

[Xianwen Chen]

Hi Grischka,

Thank you for testing the code.

Which version of tcc and on which platform were you running it? 'cause I got a different output (please see attached text file). I'm running tcc 0.9.25 on Windows 7, using binaries from:

http://download.savannah.nongnu.org/releases/tinycc/tcc-0.9.25-win32-bin.zip

In the output I produced, value of b changed to 9.752515, which is value of x2 when polynomial was first called.

Hi,

Please have a look at the attached c code -- I'm writing a function to solve polynomial problems. The issue is that variable b's value changes when the function polynomial was called for the first time.

I'm using version 0.9.25 windows binary from the website.

"tcc -run WTP_computation_test.c" here produces the text
below.  What is wrong with it?
